AUTOMATlC LIQUID CONTROL.

Application filed May 25, 1925. Serial` No. 32,?04.

To all whom t may concern.'

'Be it known that I, EDWIN E. JosLiN, a citizen of the United States, residing'at Portland, county of vMultnomah,` and State ot Oregon, have invented ya new and Auseful Improvement in ain Automatic Liquid Control, ot which the following is a speciiication. Y y i' rhe applicant herein has a pending application of the United States Patent Oiiice, tiled March 6, 1923, Serial No. 623,207, tor an automatic liquid control. y

In this device, as in the pending application, the same ,is to be used for automatic liquid control, lfor use in buildings", apartments, hotels, factories and like places where wat'cris to be drawn in volume with alight head pressure at intervals and wherein the same may bereiilledagain betere being used.

Further objects ot `'mypresent invention consists in a master control box into which liquid, under a substantial head2. is dis.-

cliarg'ed y'therein and having' a float control for operating t-he inlet vval-ve ot the liquid to be deposited therein under pressure.

Further novelty resides in the float construction and the operation of the same in the master control box.

Further novelty resides in the shape ot the discharged terminal leading from the master control box to a series ot one or more ot said boxes to be located at levels below that oi the master control box.

Further novelty resides in the float dis charge control leading from the master oontrol box to that of the series located therebelow.

Further novelty resides in the means adapted to draw flushing water from any one ot the lower individual flushing tanks, in the series, and to refill the same from others in the same series.

Tith these and incidental objects in view, the invention consists in certain novel features oit Construction and combination of parts, the essentialV elements of which are set i'orth inl the appended claims and to a preferred torni of embodiment ot which is hereinafter shown with reference to the drawings which accompany and form a part ot this specification.

For a more complete description of my invention, reference is made to the accompanying` drawings in which,-

Fig. 1 is a side elevation, partially in section, of the master control box and the Series dispose-d therebelow and illustrates the means supplying the liquid tromthe master control to the series disposed below the same.

Fig. 5 is a sectional view taken 'on line 5-5 of F ig. 6 lookingin the direction indicated.

-.F ig. 6 is a plan view ot one oi' the series disposed below the master control bon.

Like reference characters reier to like parts throughout the several views.

1 is the master control box having a closure 2 disposed thereupon and having a transverse partition 3,5vthe top of which is disposed somewhat above the center line of' the control box as shown in Fig. t. 5 is a pipe leading from the liquid supply to the Control box having suitable fastening nuts 6 and 7 to facilitate the passage ot' the liquid pipe 5 through the wall of the mastercontrol boX. A suitable valve is disposed in the discharge end ot pipe 5 adapted to being manipulated by the lever system 8. A Heat 9 is hinged about the pivot support 10 and terminating in the crank 11 for maniplating the valve operating lever 8. The drop of t-he float 9 into the dotted position as shown in Fig. 3 opens the valve and the liquid to be admitted is discharged through pipe 12 terminating in the bend 13 `disposed at the lower end of the same and arranged to impinge the discharge liquid upon the float 9. The master control box is divided into compartments 14 and 15. The liquid is discharged from the source of supply into the compartment 14 and is transferred from compartment 11i to compartment 15 through siphon 16. Leading from the compartment 15 is a discharge pipe connectingthe master Control box with a series ot flushing tanks 17 and 18 disposed therebelow. The discharge pipe 16A terminates inthe curved terminal 19 adapted to discharging liquid, at or near the bottom of the flushing tank 17. The normal position of the siphon 16 is shown in the full line position of Fig. el, Attached to this siphon is a chain pull 20 passing over the pulleys 21.

and 22 and connected to the siphon by suitable means as shown at 23. r1`his chain pull terminates on this lower end in a float 24:. The float is of sutcient weight, when not buoyed up by the liquid in the tank 17 to torce the siphon 16 into the dotted position as shown in Fig. 3, which permits of the discharging of the liquid from compartment into the flushing tank 17, but the buoyancy of the liquid entering` the flushing tank 17 raises the float 24 thus permitting the siphon 16 to raise to normal position as shown in Fig. Ll; thus when liquid is withdrawn from the flushing tank 17, the float 211 will fall and liquid will be drawn from the master control box 1 to the flushingl tank 17, but as soon as the supply has gone to the supplying' of the flushing tank 17, the buoyancy of a liquid therein will raise the float and cut ofi the liquid to be discharged through the pipe 16.

Connecting the flushing` tanks 17 and 18 is an inverted siphon 25 which maintains the equilibrium level in the flushing tanks 17 and 18. To facilitate the filling of the inverted siphon, or the drawing' ot air therefrom1 the cock 26 is provided at the highest point in the inverted Siphon 25.

lllhile the form ot mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that itis not intended to coniine the invention to the one form of embodiment herein shown and described, as it is susceptible ot embodiment in various forms, all coming within the scope of the claim which follows.

What I claim is An-automatic liquid control, comprising a master control box having an inlet compartment and a discharging compartment formed by a transverse partition disposed thereacross, the upper surface of which is disposed substantially below the upper, outer surfaces ott the outer walls of the box, the receiving' compartment ot' said master control box being connected to a source of liquid under pressure, a iioat controlled valve admitting liquid from said source when the level of said liquid is lowered in the inlet compartment of said box, an inlet pipe having` its inner end disposed below the inlet valve and being curved upwardly and so disposed as to impinge the discharging liquids upon the vfloat contained therein to impart an upward movement thereto, a yoke siphon disposed over the transverse partition and adapted to pass liquids from the inlet compartment within the box to the outlet comiartment of said box, said siphon adapted to be oscillated about a fixed bearing within the box and to actuate the float controlled valve to admit liquid within the inlet compartment within the box, a series of one or more secondary flushing` tanks disposed below the master control box and a communi- EDXVIN E.
